walls, at the desired site, locate and mark the
wall studs.
NOTES:
• For ideal installation secure the base plate
to at least one wall stud
• Drywall KapToggles can be used for holes
not aligned with studs.
• Always use the widest spacing of screws
and KapToggles.
• The base plate can be installed over an
existing electrical outlet.
g. Hold and level the base plate against the wall
and mark the positions of the slotted mounting
holes that are on the stud lines (see image at
right). Where applicable, mark the mounting
holes on the wall for drywall toggles.
h. If the cables are to be run behind the wall to the
WMK 160 location, mark the cutout area on the
wall for the signal cable access hole and cut out
the marked area.
i. Drill 1¾ inch (4.4 cm) deep pilot holes at the
hole marks.
j. At the pilot holes, screw in the screws until a
gap of about 3/8 inch (9 mm) remains between
the wall and the screw heads.
k. Align the slotted mounting holes in the base
plate over the installed screws, then slide the
plate down so the screw fit into the slots.
l. Verify level and position, and tighten down all
the screws to secure the plate flush to the wall.
NOTE:
If using toggle assemblies, see figure at
right for method.
